Impactos da NBR 5422 no equilíbrio entre o desenvolvimento e a preservação ambiental

Abstract

The NBR 5422 (Brazillian Standard) has a crucial role in the planning and construction of transmission lines in Brazil, establishing technical guidelines that aim to ensure safety, efficiency and suitability to the needs of the sector. This paper evaluates how this standard addresses environmental impacts, discussing their causes and effects. The research identifies the main factors associated with the environmental impacts of transmission lines, with emphasis on the right of way, in addition to evaluating the incorporation of new environmental criteria and methodologies that improve the accuracy of technical calculations. To exemplify the impacts and advances provided by the changes in the methodology for calculating the right of way, a case study was carried out simulating a transmission line connecting the capitals of Campo Grande and Cuiabá. The results obtained through the case study and the analysis of new methods of land use and occupation highlight the relevance of the normative as a tool for mitigating environmental impacts, evidencing the importance of an integrated approach between technical criteria and sustainability.
